A very primitive equation believed to be true by man, who, as result, prevented women from achieving many great things (more than what they've achieved now) by causing them to believe it as well. Of course it has been disproved by many women throughout the course of centuries, but many sexist men and some idiotic female followers struggle to grasp this.

Men=Women

Men>Women = Wrong

Man: Men are always better than women, no matter what. They belong in the kitchen. Bitch where's the sandwich I asked for?
Woman: LMAO Asshole please, you work at Subway, you're making me sandwiches everyday. Go get it yourself.
